Effects of Prenatal Maternal Stress on Development

Summarise the factors which may influence the health and development of babies in the first year of their lives.

The research is discussing the effects of prenatal stress (PS) on the development of socioemotional symptoms as well as neurodevelopmental disorders. The study arises from existing literatures where a significant relationship has been established between prenatal stress and social deficits such as autism and attention-deficit hypersensitivity disorder among children and schizophrenia among adolescents. King et al. identifies exposures to environmental hardships and stressful events as the underlying factor in the development of PS (274). The aspect has a negative impact on the immune and endocrine system as well as neurological development (Charil et al. 56). Studies have revealed that PS affects several aspects of brain development in the fetal stage. It increases rate of cell death and reduces rate of proliferation in the hypothalamus-pituitary axis (Schoenfeld and Gould 15).

Whilst the mother is pregnant if the baby is exposed to toxic chemicals, foods of a certain kind, or also stress from the mother then this can permanently change the cognitive development. Infancy is one of the main times when the child begins to develop their intellectuality so this means that if any of the above have been exposed to much to the baby, when they are going through infancy they may struggle with their cognitive development. Those mothers that smoke, eat unhealthy foods or go through stress or trauma whilst they are pregnant usually notice a risk of delayed cognitive development when the child is an infant. On the other hand if the mother doesn’t smoke, eats healthy and remains stress and trauma free whilst going through the pregnancy, the infants cognitive development is usually normal.

Development of children begins at conception however the parent’s health and lifestyle prior to conception could influence a baby development.

A second suggested activity during pregnancy could be for the pregnant woman to take care of herself psychologically and emotionally, to ensure that she is not too stressed or experiencing anxiety. Regular relaxation could be advised by taking up yoga and meditation. Too much prenatal stress can have negative developmental implications for the child later in life. Research has indicated that when mothers-to-be have high levels of pregnancy-specific anxiety, their offspring were significantly more likely to show lower inhibitory control among girls, and lower visuospatial working memory performance among girls and boys (Buss et al., 2011).

As a child is developing in the womb, its development can be affected at this time, for instance if the mother smokes or uses drugs or excessive

The prenatal period is when quick changes in the fetal organs are vulnerable to organizing change and stability but also building internal working system to trigger emotional responses (McEwen et al. 2013). It is a critical time for brain development and the PFC (McEwen et al. 2013). It exposes a selection of long -term modifications on brain development and behaviour (Entringer et al. 2009). Prenatal exposure to stress affects hormones in the body including the physiology and anatomy that relate to increasing drug levels, cortical communication and more (Entringer et al. 2009). Fetal stress is any event that interrupts a fetal process in stability in the body. (Entringer et al. 2009). During pregnancy, maternal stress impends the fetal nervous system and shortens the length of maturation due to many issues and concerns affecting the mother (Entringer et al. 2009). During pregnancy, maternal psychosocial stress threatens the fetal nervous system and contracts the length of gestation (Entringer et al. 2009). High levels of placental corticotrophin- releasing hormone

Between conception and birth, babies can be affected by the health of their mother as well as her lifestyle choices. Stress, deit and alcohol are examples of factors that can affect development. It is now recognised that the first twelev weeks of pregnancy is when the foetus is at it's most vulnerable. During this time the foetus

Technological advances in the past decade have allowed scientists to study the brain in ways that have led to new understanding about how young children develop. There is a new understanding of both the capabilities and the vulnerabilities of infants and young children and that understanding is has influenced the work of caregivers and teachers. During pregnancy, the basic architecture of the brain is formed. Although, certain experiences do influence the developing brain during pregnancy, such as maternal health and stress, intake of drugs and/or alcohol, and quality of maternal nutrition.

As previously mentioned, environmental factors, such as exposure to taratogens, can affect the development of the unborn child. Broderick and Blewitt (2105) define a teratogen as “substances or agents that can cross the placental barrier and produce fetal deformities when taken or absorbed by the mother during pregnancy” (p.619). These substances include drugs, alcohol, cigarettes, pollution, stress hormones, poor nutrition, and diseases, such as AIDS. Consumption of drugs and/or alcohol can lead to low birth weight, as well as, physical, cognitive, and behavioral abnormalities. Furthermore, more recent studies are showing that exposure to pollutants can affect an individual’s development. For example, a study of the

A mother who struggles with depression post-partum is likely to expose her baby to more harmful effects. Gerhardt (2015) states that the baby of a depressed mother can find it difficult to cope with or get over stress, or they may be more fearful (p. 21). These babies also may respond to others with depression themselves, as their mother may be neglectful in their care (Gerhardt, 2015, p. 36). One of the reasons for this is because of their cortisol levels, which can fluctuate situationally. However, in infants this can affect their development (Gerhardt, 2015, p. 83) as well as their immune system (Gerhardt, 2015, p. 118), and is evidence that a mother with depression can have a significant impact on her child well beyond when the depression occurs. Additionally, Gerhardt (2015) notes that, “When they grow up, these babies of depressed mothers are highly at risk of succumbing to depression themselves.” (p.

Infants are very helpless and extraordinarily dependent. Their earliest behaviors are goal driven for gaining a caregiver to focus and engage reciprocity in their behavior (Sroufe, 2011). The infants task is to gain their survival needs and regulate fear and stress by creating contingent responses so that the world may be predictable and comprehensible (Sroufe, 2011). Regulating emotions can only occur in relationship with the parents; an infant is ill equipped to reduce arousal on their own (Seigel, date, Sroufe, 2011, cite.) The infants work is most effective when circumstances and contingent responses are anticipated and more challenging when they encounter unpredictability and transitions (Hughes, 2014).

At one time or another, most people experience stress. The term stress has been used to describe a variety of negative feelings and reactions that accompany threatening or challenging situations. However, not all stress reactions are negative. A certain amount of stress is actually necessary for survival. For example, birth is one of the most stressful experiences of life. The high level of hormones released during birth, which are also involved in the stress response, are believed to prepare the newborn infant for adaptation to the challenges of life outside the womb. These biological responses to stress make the newborn more alert promoting the bonding process and, by extension, the child's physical survival.

The unwanted children born weighed less at birth and needed more medical care even though the mothers were judged to be in good health. Fewer of the children were breast fed, they had more difficulties in school, and they were referred for psychiatric help more often as teenagers. Also that by the time they had reached adulthood, many were more likely to have antisocial behavior problems. So here we can see from this research that stress also plays a vital role of a healthy developing baby.

Having taken this class I have come to understand a lot about my emotions and why I feel the way that I do about certain things throughout my life. Stress is something that has weighed heavy on me since a very young age. I have always wondered why I seemed to not be able to handle stress as well as my peers. Then I came to understand that mothers who experience high levels of stress during pregnancy release high levels of cortisol, and in turn this can have a lasting effect on the baby. (Wood, et. al., 2014) This includes the child not being able to deal with stress as well as he or she grows up and even an increased chance at the baby suffering from high blood pressure later in in life.
